Verse 20 repeats the substance of verses 17 and 18 and adds nothing new. Made over to Abraham translates the same verb as used in verse 17, which Revised English Bible renders “became the legal possession of Abraham.” The sense is “was sold to,” “was transferred to.”

As a possession for a burying place: see Gen 23.9. In some translations burying place is expressed more fully as “a place for burying [dead] members of his family.”
